Catpiss Neverclean : A Reprisal

I'm not sure if anyone reads these, but my cat started peeing on things. Again. Last night she peed on the bed while my girlfriend and I were in it. I made an appointment for her to go to the vet in case she has a uti or something more serious. 

I'm worried though that the vet won't check her out adequately. She's a little vicious, and tends to struggle when she's removed from her environment. She's not really acting differently because she's always a bitch, so nothing new there. She always yells at me when I'm there and cries when I leave. She's peed all over my bed at this point, thankfully I have a waterproof cover for it. She's peed all over my couch and we got the smell out but the texture is weird. We shampooed the carpet in the hallway and so far both Briar and Winda are doing good about not peeing on it. 

I'm just frustrated and over it. She's an older cat, I got her in July 2008 as a baby, so idk if this is the demise of her continence or maybe she's not too old? My anxiety is like whoa lately so this doesn't help. I just want her to be okay and to stop peeing all over my stuff. 

Positive : I'm going back to therapy [tentatively], and I [tentatively] found someone for my thigh tattoo I've been dying to get for YEARS now. Helloooo anxiety!
